基于PHP Socket配置以及实例的详细介绍

复制代码 代码如下:

<?php
//phpinfo();
//确保在连接客户端时不会超时
set_time_limit(0);
$ip = '127.0.0.1';
$port = 1935;
/*

+-------------------------------
* @socket_create
* @socket_bind
* @socket_listen
* @socket_accept
* @socket_read
* @socket_write
* @socket_close
+--------------------------------
*/
/*---------------- 以下操作都是手册上的 -------------------*/
if(($sock = socket_create(AF_INET,SOCK_STREAM,SOL_TCP)) < 0) {
echo "socket_create() 失败的原因是:".socket_strerror($sock)."/n";
}
if(($ret = socket_bind($sock,$ip,$port)) < 0) {
echo "socket_bind() 失败的原因是:".socket_strerror($ret)."/n";
}
if(($ret = socket_listen($sock,4)) < 0) {
echo "socket_listen() 失败的原因是:".socket_strerror($ret)."/n";
}
$count = 0;
do {
if (($msgsock = socket_accept($sock)) < 0) {
echo "socket_accept() failed: reason: " . socket_strerror($msgsock) . "/n";
break;
} else {

//发到客户端
$msg ="测试成功！/n";
socket_write($msgsock, $msg, strlen($msg));

echo "测试成功了啊/n";
$buf = socket_read($msgsock,8192);


$talkback = "收到的信息:$buf/n";
echo $talkback;

if(++$count >= 5){
break;
};


}
//echo $buf;
socket_close($msgsock);
} while (true);
socket_close($sock);
?>
